Responsibilities
- Design and deploy semantic chunking models for lengthy, non-uniformly structured legal documents with adjustable granularity across use cases
- Build document enrichment systems using legal and customer-defined taxonomies
- Develop LLM-based knowledge graph construction pipelines that extract and link citations, entities, and legal concepts across diverse legal content
- Lead knowledge distillation efforts to compress large models into latency-constrained, production-ready SLMs
- Design evaluation frameworks — component-level and end-to-end — using expert annotation and synthetic data
- Own technical decisions on architecture, chunking strategy, classification approach, and knowledge extraction methods
- Partner with engineering on delivery, reliability, and scale across multiple product lines
- Provide technical input to senior leadership on AI strategy and roadmap
- Mentor applied scientists and ML practitioners on the team

- Hands-on production depth required in: Knowledge distillation, model compression, and SLM deployment under latency constraints
- Hands-on production depth required in: Synthetic data generation and annotation workflow design
- Hands-on production depth required in: End-to-end evaluation framework design for document understanding
- Legal document understanding, legal IE, or legal AI experience
- Complex document structures: nested hierarchies, cross-references, non-uniform formatting
- Retrieval or QA systems over large document collections
- RAG and agentic workflows in enterprise settings
- Knowledge graph frameworks for legal or enterprise applications
- AzureML or AWS SageMaker
